Adding sites to your 'blocked' list is easy - just go the the LeechBlock extension in your add-on manager and click 'Options' to add a site.

If you can't help yourself, then LeechBlock will track the amount of time you've spent on blocked sites. Principally though it's been designed for those with a wandering mouse cursor, which is why it even allows you to set a password to access prohibited sites to help "slow you down" in moments of weakness. This includes between certain times, specific moments in time, or a combination of both.

The nice thing about LeechBlock is that you can configure it to block sites between a specific time period, so you don't have to keep activating and de-activating it if you want occasional access to a site.
